What is made of chitin?
Chitin is a polysaccharide (polymer) of N-acetylglucosamine, which is a derivative of glucose. It's chemical formula is: (C8H13O5N)n ...where "n" is the monomer length of the polymer. Chitin is similar to the polymer cellulose in terms of function in biological organisms (primarily as a structural polymer), but has a completely different chemical structure.
